  1. Hello,
    I tried following your instructions on this page to get the dolby home theater V4 installed on my lenovo t430 laptop that’s currently running windows 11 pro 64-bit edition. I’m thinking that part of my install issue is the fact that I’ve already got a version of dolby digital plus advanced audio (version installed on my laptop. And of course I’d much rather have dolby home theater V4 installed on my laptop due to the fact that it has additional features compared to the dolby digital plus advanced audio application that’s currently installed. Also, by having the secure boot option activated I’m thinking that’s contributing to my issue. I’ve already went into the advanced settings area and supposedly disabled the driver signature enforcement feature in that area by selecting #7 option. Of course I’d like to get the version of dolby installed properly but I’m wondering if I’ll in fact be able to at this point. Can you please offer me any suggestions concerning my issue ? Thanks in advance for any & all help you might provide.
